I changed my Agility's motor oil few weeks ago and then noticed that kicking doesn't start the engine no more. It almost makes it run and few rare occasions it has started for few seconds bu kicking.
Electric starter works and the scooter usually start with the first try.
Then this thing escalated and it didn't start with either one. I check spark, it was okey. Cleaned carburetor and adjusted valves. Checked electric richer that it works. Checked that there were no air leaks in the manifold or elsewhere in the carburetor. Now I got it to the point as it was earlier, so electric starter works but kick starter almost makes the engine run but will fail after several attempts. I have opened the variator several times and cleaned and oiled things accordingly and all is fine "down there" and the kick start seems to be working as it should, but it just doesn't get the engine going...
I got a hint elsewhere to check compression for the cylinder cos there might be leak in the cylinder head gasket perhaps. But I don't have a gauge for this test.
Has anyone else had similar symptoms and what else should i still check?
